Abstract

The article examines methods for protecting buildings against internal explosions through the implementation of safety rotary structures. The study analyzes various approaches to structural safeguarding during internal blast events, with particular focus on different types of safety structures and their operational parameters. The research investigates the determination of gas venting areas in buildings using rotary mechanisms designed to ensure occupant safety. Key parameters such as the sealing depth and flap thickness of safety structures are evaluated for their role in forming effective gas outflow zones. The work establishes a functional relationship between the dimensions of the safety structure flap and the resulting area for primary gas venting and pressure relief. Additionally, the study comprehensively considers the influence of safety structure embedment depth and material thickness on blast mitigation performance. These findings provide valuable insights for optimizing building safety systems in explosion-prone environments.
